1200mg/Nm3, dust concentration 20～30g/Nm3, the oxygen content 8%～12% of flue gas, the water capacity of flue gas
15%～25%, the flue gas of domestic waste incineration 1 enters reaction tower 11 by the suction function of main air blower 38,
Flue gas is accelerated after entering reaction tower 11 at trunnion 6, and high velocity air is formed in reaction tower 11 strongly
Turbulent flow, produce efficient sufficient gas-solid contact；Through deacidification process the flue gas containing high concentrate dust from
Reaction tower 11 top exhanst gas outlet 12 out after, enter rear portion sack cleaner 18 in carry out udst separation,
Flue gas through purifying flows out sack cleaner 18, enters the outer row of chimney 39 by main air blower 38 and clean flue；
When the flue-gas temperature entering sack cleaner 18 exceedes the operating temperature of cloth bag, open bypass valve 28, close
Electronic air inlet valve 2, is made flue gas pass through by-pass line 40 and enters main air blower 38, discharged by chimney 39, protects
Protect cloth bag；
Claimed 23 by calcium hydroxide dry powder feed bin 21, discharger 22, electron helical, frequency conversion rotary feeder 24,
The calcium hydroxide injection of the composition such as high pressure roots blower fan 25, mixture generator 26, calcium hydroxide playpipe 27
Device；Exhaust gas volumn according to incinerator 1 and the amount of generation acidulants, calculate Ca (OH)2Consumption, through electricity
After sub-spiral claims 23 Weighings, by frequency conversion rotary feeder 24, according to operating mode, with the side changing rotating speed
Formula adjusts powder delivering amount, and powder delivering amount sends into blender 26, from the wind-force of high pressure roots blower fan 25, will fall into mixed
The powder of clutch 26 is sent into the calcium hydroxide mouth 7 that dusts by calcium hydroxide playpipe 27 and is entered in reaction tower 11,
In reaction tower 11, spread in the calcium hydroxide particle in flue gas under mutual rubbing action, constantly hydrogen-oxygen
Change (sub-) calcium sulfate removal that calcium particle surface generates, make that the calcium hydroxide within granule is the most exposed to make new advances
Surface, makes deacidification reaction constantly be sufficiently carried out down, the SO in flue gas2Removal efficiency can reach 90%,
Due to SO3, the sour gas such as HF, HCL compare SO2It is more easy to react with calcium hydroxide, reaction tower 11
Interior SO3, the removal efficiency of HF, HCL can reach more than 90%；In reaction tower 11 reacted
Calcium hydroxide carries out calcium hydroxide repeatedly by air flume 19, reaction tower circulating line 14 with reaction tower 11
Circulation, its circulating load is controlled by recycle feed valve 13, is provided with middle pressure roots blower bottom air flume 19
20, the calcium hydroxide in air flume 19 is in suspended state all the time, it is ensured that the elimination reaction occurred,
After deacidification runs a period of time, open ash silo electrodynamic valve 15, the dust in deacidified product, flue gas is entered
Ash silo 16, discharges blood circulation by electric cinder valve 17, and calcium hydroxide induction system is by calcium hydroxide repeatedly
Circulation and smoke contacts, circulating ratio reaches 100～200 times, and calcium hydroxide utilization rate is high；
A series of chemical change is there is in above-mentioned technical process:
Ca(OH)2+SO2+1/2H2O→CaSO3.1/2H2O+H2O
Ca(OH)2+SO3+H2O→CaSO4.2H2O
Ca(OH)2+2HCL→CaCL2.2H2O
Ca(OH)2+2HF→CaF2.2H2O
CaSO3.1/2H2O+1/2O2+2/3H2O→CaSO4.2H2O
Ca(OH)2+CO2→CaCO3+H2O
In reaction tower 11, mixture is dry relatively uniform, and recycle hydrogen calcium oxide has fabulous mobility, energy
Guarantee stablizing of operating mode in reaction tower 11；Deacidification becomes the thicker granule work at gravity because of conglomeration
With falling in reaction tower taper ash collection slot 4, reacted tower bottom electric cinder valve 5 is discharged；
Secondary deacidification reaction on cloth bag: under the effect of negative pressure, Ca (OH)2Powder adsorption is formed on cloth bag surface
One layer of Ca (OH)2Bisque, reacts further with the gas containing acid fume entering cleaner unit.In course of reaction, use
Cleaner unit import and export pressure differential controls deashing frequency, when pressure differential exceedes the upper limit of setting, to cloth bag
Carry out deashing, in order to Ca (OH)2Powder constantly adsorbs on cloth bag surface and containing acid fume solid/liquid/gas reactions.Ca(OH)2
Iterative cycles and smoke contacts, Ca (OH)2Utilization rate is high, improves deacidification efficiency.
Claimed 31 by activated carbon feed bin 29, discharger 30, electron helical, frequency conversion rotary feeder 32, high pressure sieve
The injection apparatus of the composition activated carbon such as thatch blower fan 33, mixture generator 34, activated carbon playpipe 35；According to
The exhaust gas volumn of incinerator 1 and the amount of the generation harmful substance such as dioxin, heavy metal, the consumption of calculated activity charcoal
Amount, after electron helical claims 31 Weighings, by frequency conversion rotary feeder 32, according to operating mode, with change
The mode of rotating speed adjusts activated carbon conveying capacity, and activated carbon sends into blender 34, from high pressure roots blower fan 33
Wind-force, sends into activated carbon entrance 36 by the activated carbon falling into blender 34 by activated carbon playpipe 35 and enters
Entering in sack cleaner pipeline 37, the activated carbon sprayed into is to nuisances such as the dioxin in flue gas and heavy metals
Matter is adsorbed；
Water for industrial use in water tank 10 is pumped into by water pump 9 in the water jet 8 of reaction tower 11, and water is with mist
Shape sprays, and improves Ca (OH)2With SO2、SO3, the heat transfer of the sour gas such as HF, HCL, mass transfer rate,
Occur to neutralize reaction, remove the sour gas in flue gas, improve deacidification efficiency；
As can be seen here, apparatus of the present invention deacidification agent consumption is few and utilization rate high, deacidification agent granule in cyclic process
Under mutual rubbing action, the most exposed surface that makes new advances, make deacidification reaction constantly be sufficiently carried out, acid removal rate
Up to 90%；In whole deacidification, operation temperature is higher than dew point, and not corrosion or condensation, without useless
Water produces, and does not produce secondary pollution；Having deacidification efficiency high, investment operating cost is low, and reliability is high, energy
Consume low, safeguard easily, the advantages such as floor space is little, system length in service life, SO2Concentration of emission 70mg/Nm3,
The concentration of emission 40mg/Nm of HCL3, dust emission concentration 15mg/Nm3, it is better than GB18485-2014 standard
" consumer waste incineration Environmental capacity standard " (SO2＜ 80mg/Nm3, HCL ＜ 50mg/Nm3, dust emission is dense
Degree ＜ 20mg/Nm3), it is possible to adsorb the noxious pollutants such as the dioxin in flue gas, heavy metal, make flue gas up to standard
Discharge, it is to avoid to environment.
